first half of this year curriculum activity is to allow students to investigate the major supermarkets sweet food application of these sweeteners. Although not a very new topic, but does not search do not know what the total even more complicated than expected. One of the most hard nut to crack, is that those "sugar-free food" has been.
sugar-free food for the definition, I have been suspicious mind. International general concept is that sugar-free foods should not add sugar and starch hydrolysates from sugar, including glucose, maltose, fructose, starch syrup, Glucose syrup, fructose syrup and so on. However, it must contain the corresponding sugar substitutes in general the use of sugar alcohols or oligosaccharides, such as elevated blood sugar sweeteners can replace sugar varieties.
But why have to add sugar-free food, what sweetness of sugar alcohols and oligosaccharides do? Can not no sweet吗? Seem to be no. For example, add the sugar alcohols in sugar-free cookies can be called food, and no sugar and there is no light sweet salty cookies can not be called sugar-free food; also, for example, add the lotus root starch xylitol can be called sugar-free food, and there is no压根pure sweet lotus root starch can not be called sugar-free food ... ... It appears that there is no sweet things that can not be called sugar-free food, this is not it a bit funny?
international practice now that are so confusing, things in China, there is no doubt even more confusion. The survey showed that the purchase "sugar-free food" before, must be psychologically prepared to do a good job, but eyes wide open, because nothing is impossible.
First of all, are known as "sugar-free food products" which may contain starch hydrolyzate type as sweet sources, that is, starch syrup, fructose syrup, maltose, and so on. I do not know whether the producers understand that these elevated blood sugar syrup into energy efficiency, not necessarily how much slower than sucrose. The most laughable thing is that the product has been added Glucose syrup, also known as sugar-free food - even in the small intestine of sucrose into glucose before it, and this product provides a pure glucose for the rapid increase in our blood sugar & hellip ; ... I really unimaginable, diabetes, if people buy this kind of sugar-free food, like trouble.
Secondly, now that must have a sweet sugar-free foods, which add natural sweeteners want. If, however, sugar alcohols and oligosaccharides, obviously the cost will be relatively high. Thus, the majority of our country have turned to high-performance products sweetener, especially synthetic sweeteners, such as Ansai honey, sodium cyclamate, saccharin, aspartame, etc..
However, the problem is not so easy to replace an ingredient: these things are the sweetness of sugar, hundreds of times, then the original instance formula, the Products to add 100 grams sugar 40 grams, and now only need to add a few grams of sweetener against enough, what to do to take care of the volume? Generally speaking, is not used to make filling starch is starch hydrolysates, such as dextrin, and so on. Both these things and sugar will rapidly increase blood sugar, and sugar is as easy as it is fattening, for diabetes and lose weight are concerned, as are big trouble.
Third, do not add sugar, does not mean that certain foods are good for people. Are neither even nor elevated blood sugar into energy efficient sweeteners, also have to stimulate the appetite, and promote the role of obesity. Their nutritional value is not applied to food products, may even lead to extra trouble. Abroad, such as is reported that some consumers are sensitive to aspartame, not limited to patients with phenylketonuria; have some consumers for "Sucralose" This sweetener is not efficient tolerance, ate after the cause fuzzy thinking from headaches to a variety of adverse reactions. Lot of people who are optimistic about the sugar alcohols, it may not be all the advantage, as most exposed to excessive intake of sugar alcohols may cause diarrhea, a small number of diarrheal effects, though small, is absorbed from the urinary excretion of renal heavier burden will go out.
Anyway, in my country a lot of the so-called "sugar-free" food, but there is no sugar are just absolutely does not mean that control of blood glucose is beneficial does not mean more favorable to lose weight. If we fail to look at the tags of the list of ingredients which, is really very serious consequences ... ...
Finally, and worst that is a lot of people because some foods marked "sugar free", on the indulgence of these have been eaten is not high nutritional value of food and beverages. The so-called "first give me a reason", all kinds of under the banner of "sugar-free food" product banner in support of their sweet taste, preferences sweet drinks, highly processed food taste bad eating habits. By my watch, this is the sugar-free food brought about by the biggest trouble!
to stay away from obesity, controlling blood sugar, the best diet to eat less of any artificial or sweet food, many eat beans potato coarse, natural texture of fresh fruit to replace sweets and sweet drinks, do not put their hopes in what sugar-free, low sugar foods.
